ORA-1000 : max open cursors exceeded

 when calling some specific application logic, the number of open_cursors  ORA-1000 : max open cursors exceeded. is increased with one.
 select a.value, s.sid
 from v$sesstat a, v$statname b, v$session s
 where a.statistic# = b.statistic#  and s.sid=a.sid
 and b.name = 'opened cursors current'
We would like to know which SQL is behind ...

Any idea how to identify such statement ?

Thanks in Advance,
Dina
